327 chevy motor in Rochester New York

[ronebee]

A friend of mine has a 327 motor in his garage and is trying to figure out what it is. Casting number on the back of the block is 3914660, number on front pad is
18D137046 T1208HM, anybody have any ideas what hes got? He says if he remembers right that it is a 4 bolt main.

all 327's were 2bolt mains ( unless converted after)

3914660....327.....68....2bbl casting number reference


HM 1968 327 w/tur hydramatic 250hp 4bbl suffix codes
from full size car

I've got one in my shop as well, chris is right with the application - as I took mine out of a '68 Impala in a junk yard. I only took the engine because it was attached to a TH400 that I wanted - couldn't leave the engine behind with only a $100 price tag for both!

Thank you for the input, I didn't know what it was and I told my friend I would post here to see if he had anything.
I learned something today, never knew that all 327's were two bolt mains, assumed all Corvette 283 and 327s were four bolts, now I'm curious to drop the pan on that motor and see if somebody modified that to a four bolt main.

I believe a scarce few 327cid's were released in 4 bolt configuration from the Romulus Mi. plant.I can't prove it,find their applications nor find the evidence that I saw to prove it,but have seen a few of them in my life and fully believe they were not modified after the fact.

Rick, what were those 4bolt 327s in? Or, what year were they from? I once had someone insist his 69 327 was a 4bolt.

Interesting, I have a 396 recorded vin stamp 18D136034 with a date stamp of 1208 just like your engine. Fits into my list perfectly! If anybody has any original fullsize engines or Muncies, please send me the stamped info off them, as I have a list of over 4000 engine dates so far and it has become very interesting research.

A guy here in Sweden who has sold used Chevy V8´s for decades claims to have stumbled over a couple of 4-bolt 327 engines to. They were not modified since they hadn´t been taken apart before.

Now I'd really like to get some casting numbers and dates on these Has any one seen any reference that claims they exist?

Has the pan been pulled in Rochester yet?
